Magazine Tube Extension with Barrel & Tube Clamp

• Includes the tube extension and extended spring
• Aluminum with black anodized finish
• Adds capacity for 3 additional rounds (2 ¾” length) or 2 rounds (3” length)
• Compatible ONLY with the GForce Arms 12GA tube feed models GF1 (Semi Auto), GFPG3 (Pumps) and most other Turkish manufactured shotguns.  NOT compatible with the GF2p, GF Pumpernickel or GFP3 Walnut shotguns.

IMPORTANT:  If your model has an “inward curl”  on the tube to prevent the spring and follower from coming out when the cap is removed (can be checked by removing the mag tube cap, pressing down on the spring follower in the tube, and feeling the edge of the tube), then installing this product requires a permanent modification to the existing tube which can VOID your limited lifetime warranty.
